To clarify, I didn't mean to say I recommend all students should be allowed to carry knives in school (although I would be open to considering this policy as well). I only said "if circumstances dictate" for example if a child is being harassed or bullied. In that case, permission to carry some form of self-defense aid (not guns) is only granted to that child.
Similarly for teachers, I said they should only be allowed to carry guns if extreme circumstances dictate. But teachers should be allowed to carry knives, pepper spray, etc under any circumstances.
Anyway, I looked up Hawaii weapon law briefly, and from what I can tell it seems to be the following (please correct or comment if wrong):
1) All switchblade or butterfly knives are forbidden, period. Zero tolerance, they can't even be owned.
2) Folding knives are okay and in general can be carried by anyone, no restriction on size or age.
3) Daggers, firearms, or other deadly weapons cannot be carried. (Even an unconcealed dagger? This makes no sense to me.) There is no mention of swords though. Perhaps that was left vague on purpose. I like swords/daggers so I'm interested to know what the deal is here with them.
4) Any further laws prohibiting weapons, such as in schools or colleges, are written/scattered elsewhere. I haven't found them (would like to) but presume they exist.
Back to the thread topic, I also saw on the news today that people are now considering whether or not elementary schools should hire security guards. I don't know if high schools have security guards. UH certainly does. But security guards can carry weapons/firearms, right? Otherwise they won't be much of a security guard.
